An adsorbent includes a binder-converted zeolite portion formed from x wt % kaolin clay binder and (100?x) wt % unconverted Zeolite X with a silica:alumina molar ratio of about 2.5. The kaolin clay binder is in the range of about 10 to about 20 wt %. Ba and K occupy cationic exchangeable sites within the adsorbent. K is in the range of about 0.25 to about 0.9% by weight and Ba is greater than about 31.6% by weight of the binderless BaKX zeolitic adsorbent. Cornstarch may be added to the Zeolite X and kaolin clay binder to increase adsorbent macro-porosity and pore volume. Productivity of the adsorbent is improved decreasing process operating costs. The mechanical strength of the adsorbent is also improved.Type: ApplicationFiled: September 5, 2012Publication date: December 27, 2012Applicant: UOP LLCInventors: Linda Shi Cheng, Jack Hurst

Publication number: 20120264992Abstract: A zeolite X having (a) a Si/Al framework mole ratio in a range from 1.0 to 1.5; (b) a mean diameter not greater than 2.7 microns; and (c) a relative LTA intensity not greater than 0.35, as determined by x-ray diffraction (XRD). The relative LTA intensity is calculated as 100 times the quotient of a sample LTA XRD intensity divided by a reference XRD intensity of an LTA-type zeolite material. The intensities are summed for each LTA peak with Miller indices of (2 0 0), (4 2 0), and (6 2 2) at 7.27±0.16°, 16.29±0.34° and 24.27±0.50° 2?.Type: ApplicationFiled: March 22, 2012Publication date: October 18, 2012Applicant: UOP LLCInventors: Jack E. Hurst, Linda S. Cheng, Robert W. Broach
